For the steer deal I know there is cheating going on, but most the time the ones winning aren't cheating. It is the ones trying to catch the ones winning that are cheating. The winners are the ones usually accused of cheating by the ones who are actually cheating. (not all the time but more times than not)
As far as airing, from what I understand about it, they do it when the calf is young, by the time they are fat steers it is almost impossible to tell they have been aired, until the hide comes off, and you need to be looking for it then to see it.
As far as the age thing on heifers, I have no solutions for you there. Like stated before the Judge, judges what he has in the ring as it is represented to him and makes his selection from there.
